IT IS OBJECT OF THE INVENTION TO REDUCE THE NUMBER OF FIELD MEMORIES FOR A CONVERTING APPARATUS FOR NON-INTERLACED SCANNING. THREE FIELDS MEMORIES 53 TO 55, A Y/C SEPARATOR AND A MOTION DETECTOR ARE ARRANGED ON THE CONVERTING APPARATUS. BASED ON A LUMINANCE SIGNAL AND A COLOR SIGNAL WHICH ARE GENERATED BY THE Y/C SEPARATOR, THREE LUMINANCE SIGNALS AND COLOR DIFFERENTIAL SIGNALS ARE GENERATED FOR A SAMPLE (BASE) LINE AND A COMPLEMENTED LINE. THE THREE LUMINANCE SIGNALS AND COLOR DIFFERENTIAL ARE SELECTED BASED ON A DETECTED RESULT OF THE MOTION DETECTOR. WHEN THE SELECTION IS CARRIED OUT, THE LUMINANCE SIGNAL AND THE COLOR DIFFERENCE SIGNAL FOR A MOTION PIXEL ARE SET TO THE LUMINANCE SIGNAL AND THE COLOR DIFFERENCE SIGNAL WHICH ARE GENERATED BASED ON THE NEWEST IMAGE SIGNAL.(FIG. 1) |
